Here's some ideas to make green smoothies, I thought I'd start off by posting a few ingredient ideas that I've tried. I'm no expert and I'm learning all the time

So please feel free to add whatever takes your fancy and agrees with your blood sugars. I try and stick to 80% vegetables & 20% fruit ratio, and find this does keep blood sugars within range. However, I have experimented with 60:40 ratio and it all depends on choice of ingredients as to whether this causes a spike or not... So please test test test.
Eg 1 orange in a green smoothie spikes me but might not effect someone else's blood sugars! Yet I'm ok with banana, pineapple and coconut!
I know it's weird!!!
